One of Germany’s 4 or 5 largest and highest autobahn viaducts, the Neckar Valley Weitingen is innovative for its two end spans. Each consists of an inverted cable stay tower that supports a massive beam span of 863 feet (263 mtrs). Similar to a king post truss, these are the largest inverted cable stayed spans in the world. The locked coil cables are 105 and 120 mm thick. The central towers in the valley are octagon shaped while the slope towers that support the cable stayed spans are framed double columns. The span configuration is 233 + 134 + 134 + 134 + 263 meters.
